Heres a simple way to program your bench. I have used it and had a few training partners make great gains with it.

Back off your best triple and pick a weight that you can use for 5x3. Use that weight on week one and add five pounds a week. If you miss a set (weights too heavy not a bad day) then you need to go up five pounds a week the next week but drop that set. Keep going adding five pounds a week until you finish with a big pr. Then you have a new triple to use for a new training cycle.

The number one goal is to keep adding those five pounds without dropping a set. If you miss and the next week you think you can get the extra set, then go for it. If you make it then chalk the miss off to a bad day and keep the set. Its simple and effective for the patient lifter.
